[dynarmic] fix SignedDiv64 crashing if immediate constprop took effect; also fix result for 0x8000_0000/0xFFFF_FFFF not returning properly for SignedDiv32 ( #3517 )
...
a program could crash the emulator by just using div immediates and/or dividing by
0x8000_0000_0000_0000/0xFFFF_FFFF_FFFF_FFFF
X0 = 0x8000_0000_0000_0000
X1 = 0xFFFF_FFFF_FFFF_FFFF
SDIV X2, X0, X1
SDIV X2, X1, X0 <- crashes emu

[*] change all std::unordered_map and std::unordered_set into ankerl::unordered_dense::map/set variants ( #3442 )
...
mainly doing this to reduce memory footprint; we all know how nice ankerl::unordered_dense is
in theory 4x faster - in practice these maps arent that "hot" anyways so not likely to have much perf gained
i just want to reduce mem fragmentation to ease my porting process, plus it helps other platforms as well (ahem weak Mediatek devices) :)

[dynarmic] simplify assert macro usage (Only ASSERT/DEBUG_ASSERT are needed) ( #2890 )
...
- replace instances of ASSERT() with those where UNREACHABLE() should be used instead
- debuggers exist for a reason, you can't just debug an issue in dynarmic with just printing fancy text... you need to inspect values and alldat - while yes the asserts are "useful"; there is this beautiful thing called backtraces
- this will indirectly speedup the main decoder loop because of the added UNREACHABLE()
- this also removes a bunch of macros that were redundant
- the weird trick of [&](){}() is really funky, just do what everyone has done for the past 30 years and use a `do { <thing> } while(0)` :)
I may or may not have missed one assert or messed up my regex substitutions...

[cmake] refactor: Use CPM over submodules ( #143 )
...
Transfers the majority of submodules and large externals to CPM, using source archives rather than full Git clones. Not only does this save massive amounts of clone and configure time, but dependencies are grabbed on-demand rather than being required by default. Additionally, CPM will (generally) automatically search for system dependencies, though certain dependencies have options to control this.
Testing shows gains ranging from 5x to 10x in terms of overall clone/configure time.
